FREDERICK J. SPITTLER, l01E" LONG ISLAND CITY, NEVI YO* fi- DEMO'UNTABLE WHEEL RIM.

Application led September 15, 1923. Serial No. GGMBSZ.

To all 'whom t may concern:

Be it known that l, FREDERICK J. SPITTLER, a citizen of the United States, and a resident of the city of New York, Long Island City, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Dernountable ill/'heel Rim, of which the following is a full, clear, and exact description. l

This invention relates to improvements in vehicle wheels, and has particular reference to a deinountable rim therefor.

An object of the invention is to provide an improved demountable rim of simple construction, wherein the sections thereof may be readily and quickly assembled and secured on the wheel and disassembled when changing a tire. 4

The above and other objects will appear more clearly from the following detail description when taken in connection with the accompanying drawing, which illustrates a preferred embodiment' of the inventive idea.

In the drawing Figure 1 is a side elevation, partly bro-ken away and shown in section, of a vehicle wheel constructed in accordance with the invention; n l y Figure 2 is a'section on the line 2 2 of Figure 1; and 'l Figures?, is a section on the line 3 3 or Figure 1. y

Referring more particularly to the acconti panying drawing, the numeral 4f'indicates generally a wheel having the spokes 5 and the telly 6 upon which the demountable krim and tire 7' are ada ted to be mounted.

The rim, whici comprises the essentiel features of the present invention, includes the inner and outer sections 8 and 9, respectively, each of which is provided with an annular flange 10 for engaging the bead of the tire 7 to retain the same in position. `When in position on the folly 6 the base of the inner section 8, which is of greater width than the felly 6, rests upon the felly band 8 and is provided with a lateral flange 11 against which the body portion of'the section 9 abuts when the sections are assembled.

At intervals about the peripheries of the abutting portions of the sections the'same are provided with registering lugs 12 having openings therethrough for receiving the. bolts 13 extending transverely through thetelly 6 and upon which are mounted the nuts ifi for securing the sections on the felly.

-said inner section andren-w J The inner section 8 is also provided upon its outer edge at intervals about its periphery with retaining lugs 15 that extend laterally from said edge and engage the inner periphery of the section 9.

For further retaining the sections 8 and 9 in co-operative relation the saine are provided with registering lugs 16 interspersed between the lugs 12. Each of the lugs 16 carried by the inner section 8 has projecting outwardly therefrom a stud 17 which is engageable in a key-hole slot 18 formed in the co-operating lug 16 of the outer section9. When the studs 17 are engaged in the small or reduced ends ofthe key-hole slots 18 the various lugs 12 and 16 are registered or in alignment, so that the openings in the lugs 12 will also be aligned to receive the bolts 13 thus enabling the rim and tire to be placed upon the felly of the wheel, after lvgvlich the nuts 14 may be threaded on said o ts.

To remove the rim and tire from ,the wheel and thereafter remove the tire from the rim the nuts 14 are first threaded from section 9 may be detached from engagement with the section 8 thus permitting the tire 7 to be dismounted from the latter section.

What is claimed is:

in a demountable rim, inner and outer` sections each having tire retaining flanges,

said sections also having lugs provided with registering openings for receiving fastening means for securing the rim upon a wheel, other cir-operating lugs formed' upon said sections and interspersed between the first named lugs, certain of said other lugs having keyhole slots therein, studs carried by the other lugs cfr-operating with the last` named lugs and engageable in said key-hole slots to prevent detachment 4of said sections said key-hole slots permitting of relative -rotary movement between said sections where-n 'l by one may be detachedjrom operative engagementwith the other, and retaining'lugs extending laterally from'the outer edge-of with ythe' inner periphe of the-ou Sectio.
